Generate static ARA report when necessary

OpenStack CI recently switched to object based log storage, which
cannot render ARA sqlite databases since there is no longer middleware
to do so. The Zuul inventory contains a var that allows us to detect
this situation called "ara_report_type". In the openstack gate, this
var is set to "html", indicating a static report should be generated.

We will now use this var in the log collection playbook to indicate
to that our log collect script should generate an ARA static html
report.
